The annual day aims to celebrate "the social, economic, cultural and political achievements of women. The day also marks a call to action for accelerating gender parity."
The celebrations, of course, are amping up on social media platforms.
Celebrities including Sophia Bush, Ellie Goulding and Ariana Grande signed on to open up about what the special occasion means to them, and what they hope we can accomplish for women in the future:
happy international women's day! ..... I mean week....... I mean month...... I mean year....... I mean life.....— Ariana Grande (@ArianaGrande) March 8, 2016
This #InternationalWomensDay I have a call to action for all of you!! I've teamed up with my friends at #TheGirlProject and the amazing team @EcoTools to tell stories of women's empowerment AND raise $$ for girls education! For every social media post about a woman who inspires you -- your best friend/sister/mom/idol/yourself! -- that you use the hashtag #MyTrueBeauty and tag @EcoTools, the EcoTools team is donating $1 to #TheGirlProject up to $100,000!!!! We believe that TRUE beauty comes from the inside out. That's what makes you shine. So shout out your ladies and impact the lives of girls around the world. Much love. #WhoRunTheWorldGIRLS #Empowerment #SisterSister Click the link in my bio for details!
And, in Ricky Gervais' case, use Twitter to shut down the uninformed critics:
It's #InternationalWomensDay. Don't embarrass yourself by asking why there's no international men's day. There is. Nov 19th. You're welcome.— Ricky Gervais (@rickygervais) March 8, 2016
Other stars used the day to recognize the women who have had a personal impact on their lives:

"You can be anything or anyone you want to be." It's a message every girl everywhere deserves to hear, and my sister and I are lucky because, by the time this photo was taken, we'd already heard my mom say it hundreds of times. It was so important to her to instill in us that we were capable of incredible things. When I think about what it takes to be an advocate for women and girls--on #iwd2016 and every day-- I always challenge myself to live up to the example she set for us.
And some, like Kerry Washington and Kylie Jenner, kept their support simple:
Happy #InternationalWomensDay— Kylie Jenner (@KylieJenner) March 8, 2016
Happy #InternationalWomensDay— kerry washington (@kerrywashington) March 8, 2016
Elsewhere on the Twitterverse, users are sharing messages of empowerment, support and reflection:
Every human has lived and grown inside a woman for almost ten months. You'd think that would help.#InternationalWomensDay— zandy hartig (@zandywithaz) March 8, 2016
Wanna know why we need #InternationalWomensDay?— Dara Creasey (@DaraCreasey) March 8, 2016
'Cause I still have to ask in every writers' rm: "What if we make that character female?"
The #InternationalWomensDay is not just about celebrating women, but also about reflecting on their challenges and implementing solutions.— Rt Hon Yakubu Dogara (@SpeakerDogara) March 8, 2016
And just a little bit of humor:
Celebrate #InternationalWomensDay by telling every man he's too pretty to like video games.— Dani Fernandez (@msdanifernandez) March 8, 2016
